I LOVE this bra. I do not like underwires and tend to fidget all day if I can feel the straps, wires, or bands. This is so comfortable!

I have a really hard time finding bras that are supportive and comfortable, and I'm so happy I gave these a try! I love that the straps and band are adjustable, the material is comfortable and beautiful, and the shape is very flattering. I also really appreciate how easy and flexible the return/exchange process is, as I had to do a few rounds of exchanges to get the right style and size for me. It's worth the price, highly recommend.

Non-Wire Bra Sizing

* Non-wire bra sizing can vary by preference and if you're toward the top of a size range and prefer more coverage, you may want to size up. For styles available in + sizes (designed with additional support details for our larger cup customers), we find DD's can be on the cusp - if you prefer more coverage and support, we suggest the + bra equivalent for your band size.
Btw, the size nomenclature has changed for Bra Tops. Here's the conversion:
XS=0, S=1, M=2, L=3, XL=4, XXL=5
